signor to Bakelite Building Products Co. Inc., NewXork, N. Y., a corporation of Delaware Application September 20, 1930, Serial No. 483,310 Renewed November 19, 1932 10 Claims. (01. 101-122) OFFICE I This invention relates to improvements in apparatus for and method of applying coloring to building material.

It is one of the objects'of this invention to '5 provide a novel apparatus for and method of applying coloring to a web of composition. material to produce designs or lines of demarcation thereon for the purpose of creating an effect of a plurality of individual figures on a single 10 element or strip. A further object of this invention is to provide an improved method of applying coloring material which involves the application to a travelling web of a quick drying paint, having the 15 such as duco, this is described in copending application Serial No. 279,402, filed May 21, 1928. A more specific object of this invention is to provide an improved apparatus and method of the class described, in which the coloring material is applied in a novel manner through a stencil or the like. I

A further object of this invention is to provide an apparatus and method of the class described, which is simple, effective, and well adapted for the purpose described.

, With the above and other objects in view, the invention consists of the improved apparatus for and method of applying coloring to building material, and all parts and combinations, as set forth in the claims, and all equivalents thereof.

In the accompanying drawing illustrating one embodiment of the preferred form of'the'indesignate the same parts in all of the views:

general drying characteristics of duco, and as tov the broad idea of the use of cellulose material,

vention, in which the same reference numerals Three other'shafts l0, llv and I2 are arranged in triangular formation with respect to one another, and may' also be journaled in a frame in the usual manner. Said shafts have mounted thereon stencil belt supporting rollers I3, l4, and 5 15 respectively. An endless stencil belt I6 is For the purpose of .removing any surplus paint from the stencil belt, yieldingly and .pivotally mounted scrapers l1 may be employed which engage opposite sides of the belt. v

- At the right hand side of the roller 8, asupporting roller I 8 is rotatably mounted, said roller being adapted to engage the lower side of the composition web I9. A printing roller 20, for a purpose to be hereinafter described, is mounted in vertical alignment with the roller 18 and is adapted to engage the upper surface of the web IS. The printing roller may be fed with ink or the like through the medium of an inking roll 2 I.

A cutting roller 22 is rotatably mounted beneath the web l9 and is engageable with the lower side thereof. Said roller is provided with knives 23 which are arranged in a desired form as shown in Fig. 3 to cut the web in a predetermined manner. A press roll 24 which is rotatably mounted above the web, is in vertical alignment with the. cutting roller 22.

Beyond the roller 22 a table 25 is preferably provided for receiving the cut sections of material after said sections have left a cutting roll.

A pipe 26, or other suitable feeding device, having lower perforations 21 therein, and connected with a source of coloring material under pressure,

' is mounted betwen the rollers l3, l4 and I5 and is arranged to spray coloring material through the rear of the stencil so that said material may pass thorugh the apertures of the stencil to color the .web along desired lines or in desired areas.

. In carrying out the improved method, the main supporting roll 8, the printing roll 20 and the cutting roll 22 are driven in any desired manner. An elongated sheet of roofing material, which comprises a fabric base coated with bituminous material and with a layer of granulated mineral, is fed between the stencil belt l6 and a portion of the supporting roll 8. The rotation of the roll 8 will cause movement of the web and also movement of the stencil belt which is in frictional contact therewith. Coloring material 28 is then applied through the'medium of the feeding member 26 to the rear of said stencil, and said coloring create a design thereon.

If an ordinary paint or coloring material were employed, it would not be possible to perform the operations of cutting and stacking the cut elements without smearing of thgcoloring material. For this reason, it-is an important part of the method that a quick drying paint be utilized as the web of building material to. which the quick drying paint is applied is usually quite hot after receiving its surfacing of interspersed mineral particles and such will help drive of! the volatile solvents of the paint and thereby bring about a rapid initial set. Said paint may be a cellulose mixture, as cellulose ester in a readily volatile solvent, commercially known as duco which possesses the property of drying very rapidly.

Inasmuch as the apertures 29 of the stencil belt must be separated at intervals as at 30 so that portions of the belt will not fall away, the lines of demarcation which will be applied to the web will be broken at intervals. ,For this reason, the printing roller 20 is employed, said printer having a printing plate extending around its periphery which is formed to apply coloring material to the short sections of the web which are below the portions 30 of the stencil belt. The web will therefore leave the printing roller with continuous lines of demarcation 3| thereon. Next, the web will be severed longitudinally and transversely by the knives 23 of the cutting roller 22 to produce from each side of the web a plurality of figured elements such as are shown in Figure 4.

Each of said elements is then cut inwardly from its lower edge as at 32 to form a slit for engagement with a lug 33. ihe shingles produced may be laid as shown in Figure 5 with adjacent elements in the same row having overlapping ends which are interlocked through the lugs and slits 33 and 32, and with the lower edge of one 'row above overlapping the upper edge of a row below, as shown in Figure 5, to create an effect of a plurality of brick like figures.

Although the coloring material 28 is shown as applied in the form of a spray, it may also be applied by a soft application roll, or in any other suitable manner. It is further to be understood that the stencil may be formed to produce any type of design on the web, the brick like design shown being merely for the purpose of illustration All other changes and modifications are also contemplated as may come within the scope of the claims.
